Measurements of several top-quark properties, obtained from the CMS data collected in 2011 and 2012 at centre-of-mass energies of 7 and 8 TeV are presented. The results include measurements of the top pair charge asymmetry, the W helicity in top quark decays and the search for anomalous couplings, the top quark charge, and of the ttbar spin correlation. The fraction of top quarks decaying into a W-boson and a b-quark relative to all top quark decays, R=Br(t->Wb)/Br(t->Wq), as well as, the cross sections of ttbar events produced in association with a photon or a W or a Z boson are also presented.
